Software documentation is written text or illustration that accompanies computer software or is embedded in the source code. The documentation either explains how the software operates or how to use it, and may mean different things to people in different roles. Documentation is an important part of software engineering. Types of documentation ...
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. [1] A document or standard that describes how to build such a connection or interface is called an API specification.
Special tags within source code comments are often used to process documentation, two notable examples are javadoc and doxygen. The tools specify the use of a set of tags, but their use within a project is determined by convention. Coding conventions simplify writing new software whose job is to process existing software.
The writing and evaluation criteria vary between organizations. Some of the most effective API documents are written by those who are adequately capable of understanding the workings of a particular application, so that they can relate the software to the users or the various component constructs to the overall purpose of the program.
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
Relationships to software engineering practices [ edit ] The paradigm of agreeing on an API contract first and then programming business logic afterwards, in contrast to coding the program first and then writing a retrospective description of its behavior as the contract, is called contract-first development.
A line documentation comment uses '##' and a block documentation comment uses '##[' and ']##'. The compiler can generate HTML , LaTeX and JSON documentation from the documentation comments. Documentation comments are part of the abstract syntax tree and can be extracted using macros.
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
